Oracle Siebel CRM Development lets logged‑in users alter data

CVE-2026-101454 · published 15 days ago
Summary

Versions 17.0 through 26.9 of Oracle Siebel CRM Development can be tricked by someone who already has a user account on the same server to change, delete or view important information. This happens because the software does not properly check the user’s rights when they use its configuration tools. To protect your business, restrict who can log onto the server, keep the software up to date with the latest patches, and monitor for any unexpected changes to data.
